Acetylene, C2H2, is a gas used in welding. The heat evolved for the combustion of acetylene is –33.79 kJ. If the heat capacity of the calorimeter is 5.54 kJ/0C, what is the temperature increase of the bomb calorimeter?
A population consists of six scores: 11,13,15,16,17 and 19. If a sampling distribution of size 3 is drawn from the population. Compute for the population of mean, variance,variance of the sampling distributions of the sample mean and standard error of the mean.
If the same amount of energy in the form of heat is added to 5.00 g samples of metals Ag, Al, Cu, which metal will undergo the largest temperature change? The heat capacities of the metals in J/g 0 C are: 0.235, 0.897, 0.385 respectively.
When 10.0 g KOH is dissolved in 100.0 g of water in a coffee-cup calorimeter, the temperature rises from 25.18 0C to 47.53 0C. What is the enthalpy change in kJ per mole of KOH dissolved in the water? The specific heat capacity of water is 4.184 J/g0C
a tank contains 325 moles of compressed helium gas. how many helium atoms are in the tank?
A coin tossed and a die is rolled. The outcome of the coin is recorded 1 when it show a head and 0 when it shows a tail. The random variable R gives the sum of the outcomes of the coin and the die. Compute the average value of the random variables.If two charges are fixed such that the distance r between them does not change, but the charge q1 is decreased by half, what is the new force?
two charges are not changed but they are moved twice farther than the original distance r, what becomes of the new electric force?
